U–Pb and Hf isotope analysis of detrital zircons from Devonian–Permian strata of Kotel’ny Island (New Siberian Islands, Russian Eastern Arctic): Insights into the Middle–Late Paleozoic evolution of the Arctic

“…The data presented here, claiming a Baltican affinity for the NSI, is in good agreement with comparable foraminifera faunas between the NSI and Spitsbergen, Franz Josef Land, Barents Shelf, and Timan-Pechora, which all formed part of Baltica in the Middle-Late Paleozoic (Davydov, 2016). Furthermore, a Baltican affinity is also supported by previous detrital zircon studies on older sediments (Ershova et al, 2016a) and Upper Devonian-Lower Permian sandstones of neighboring Bel'kovsky Island (Ershova et al, 2015c;Pease et al, 2015).…”

Regional correlation and seismic stratigraphy of Triassic Strata in the Greater Barents Sea: Implications for sediment transport in Arctic basins

“…A provenance shift in other Arctic basins (e.g. Chukchi basin, Wrangel Island, New Siberian Islands) was documented Miller et al (2013), Miller et al (2018 and Ershova et al (2015). Their studies suggest a close proximity to the Siberian Traps and sediments sourced from West Siberia, Taimyr and Polar Urals during the Triassic and sediment transportation across the GBSB.…”

Devonian–Permian sedimentary basins and paleogeography of the Eastern Russian Arctic: An overview

“…The characteristic feature of the Middle-Upper Devonian deposits of Severnaya Zemlya is the presence of clastic red beds, which have been interpreted as the deposits of a Caledonian foreland basin (Lorenz et al, 2008a). Upper Devonian-lowermost Carboniferous red-colored continental to shallow marine sandstone and siltstone also have been reported from Kotel'ny Island, along with an almost identical distribution of detrital zircon age populations (Ershova et al, 2015b) (Fig. 11), suggesting that the New Siberian Islands may have represented a distal part of the Caledonian foreland in the Late Devonian-earliest Carboniferous.…”
